Crystal structure of N'-[(E)-(1S,3R)-(3-isopropyl-1-methyl-2-oxo-cyclo-pent-yl)methyl-idene]-4-methyl-benzene-sulfono-hydrazide.

ABSTRACT: The title compound, C17H24N2O3S, was synthesized in order to determine the relative configuration of the corresponding ?-keto aldehyde. In the U-shaped mol-ecule, the five-membered ring approximates an envelope, with the methyl-ene C atom adjacent to the quaternary C atom being the flap, and the methyl and isopropyl substituents lying to the same side of the ring. The dihedral angles between the four nearly coplanar atoms of the five-membered ring and the flap and the aromatic ring are 35.74?(15) and 55.72?(9)°, respectively. The bond angles around the S atom are in the range from 103.26?(12) to 120.65?(14)°. In the crystal, mol-ecules are linked via N-H?O hydrogen bonds, forming a chain along the a axis.

The title compound, C17H24N2O3S, was synthesized in order to determine the relative configuration of the corresponding β-keto aldehyde. In the U-shaped mol-ecule, the five-membered ring approximates an envelope, with the methyl-ene C atom adjacent to the quaternary C atom being the flap, and the methyl and isopropyl substituents lying to the same side of the ring. The dihedral angles between the four nearly coplanar atoms of the five-membered ring and the flap and the aromatic ring are 35.74 (15  ...[more]
